I'm only hooked in to the Democratic technology side, but there is https://thedemlabs.org/ that collates (and creates) a bunch of technological solutions for campaigns problems.

I'm also personally affiliated with https://ragtag.org/ which is a bunch of volunteers trying to make said resources and tools.

We (Newspeak House) would love to see one created. If you know people in that space, put up some tech and share it. Feel free to use our template if you credit us.
